Allorney l ronso mom BACKGROUND OF THEINVENTION upper extremities of patients while they were seated on a table or gumey. The patient with a broken arm for example is usually weak and nauseous and must be supported by one or more nurses or aids. The prior art devices did not show any devices which supported a patient on an incline so that his arm would be positioned to fall away from the body for ease in applying a cast. Further, the prior art did not disclose any device which did not restrict the flow of blood to the arm when in the position just described. 2

SUMMARY The gist of the invention is to provide seating which sup ports the torso of a patient at an incline with the seat also inclined at an angle, the upper portion, of the inclined board being constructed so that the flow of blood is not restricted to the upper extremities. I

An object of the invention is to providea support for a person having an injury to the upper extremities so that castszmay be applied. Other objects are to provide a device which will hold a patient in a semierectattitude permitting less painful respiratory movements associated with multiple fractured ribs as with crush injuries of the chest;'hold the patient fixedly while aspirating the pleural cavity or performing a thoracotomy; ease the stress on the cardiovascular system; and permit dependent settling of inflammatory exudatesin-the abdominal cavity.

A further object is to provide a light weight device which may be quickly adjusted to support persons of various-size and builds, can be collapsed for storage, is easy to use and maintain, and yet is inexpensive to manufacture.

FIG. 7 is a perspective view of the device showing a patient in phantom line using the device.

FIG. 8 is an exploded view of an alternate way of making a DESCRIPTION OF THE PREFERRED EMBODIMENTS The torso tilt board of the present invention consists briefly of a base frame 1, a seat member 2, mounted on the frameat an angle from the horizontal for supporting a seated patient 3; an inclined member 4 mounted on the frame for supporting the torso of the patient; and the upper end 6 of the inclined member being contoured and positioned at an elevation to cradle beneath the arm of the patient and being formed with a depression 7 in the midportion of the contoured portion to prevent cutting off the circulation of blood to the arm.

The frame may be constructed invarious ways of various materials but is here constructed of alight weight metal tubing consisting of elongated members 8 and 9 formed in semicircles l1 and 12 at either end. Crossmembers l3 and 14 provide rigidity. v

To provide support for the seat 2 supports 16 and 17 elevate the semicircular tubular member 18. The seat is connected to the semicircular memberand may be constructed i from wood or plastic. Preferably the seat surface is without contour to accommodate different size persons either in the side or back positions as seen in FIGS. 7 and 10. A semicircular sheet member 19 rests upon the other'end of the frame.

The inclined member may be made from wood or plastic or other suitable material and is sufficiently long and wide to support the torso of a person. The frame supporting and attached to the inclined member consists of a crossmember 2lpivotally mounted on the base frame at point 22,.a U-shaped member 23 and a crossmember 24.

The inclined member is supported atan opportune elevation of 40 from the vertical by bracing consisting of a crossmember 26 pivotally mounted on the base frame at pivot 27 with struts 28 and 29 connecting angle member 31 to the crossmember. v 7

A locking means 32 releasably connects the bracing to the crossmember 24 of the. inclined member and may be any of various means but here consists of a-sleeve 33 connected to the angle member and containing a pin 34 formed with a finger engageable knob 36 anda spring retainer 37. Spring 38 biases the pinto a position through an opening 39 in the angle member and an opening 41 in the crossmember of the. inclined member. By providing additional cro'ssmembers such as member 40 on the frame supporting the inclined member, different elevationsof the inclined member are easily attained.

Preferably the upper end of the inclined member is contoured as shownin the drawings so that. the arm of the patient may be comfortably cradled. A slight incline of the sides toward the center tends to hold the arm so that the patient is supported from moving forwardly or backwardly. The con toured portion may be padded, leaving a depression at the approximate center to prevent pressure on the artery to the arms or the inclined member may be molded with an enlargement and the necessary contour and depression.

The device is collapsible to a very compact form by merely releasing the locking means, folding the bracing means down upon the base frame and permitting the inclined member to swing down upon the base frame.

In FIGS. 8, 9, and 10 is shown a modification-of the inclined member to render the device suitable for large and small individuals. The modification consists of the addition of flanges 42 and 43 formed with slots 44 and 45connected to member 23' of the frame consisting also of crossmembers 21' 24', and- 40. The inclined member 4" is modified by adding threaded studs 47 and 48 attached to plates 51 and 52. The studs are positioned in slidable registration in slots 44 and 45 and nuts 53 and 54 threaded on the studs clamp the inclined member to the-modified frame in an infinite number of positions.

A further modification of the device is shown in FIG. 11 in which the seat member 2 is pivotally mounted on the base frame at pivot 56. The means for raising the seat can be effected in several different ways, and one means is shown-in the drawing. Frame members 8. and 9 beneath the seat portion are formed with slots and sliding members such as wedges 57 formed with threaded holes for receiving bolts 58 slide thereon.

The frame beneath the seat may be provided with flanges formed with slots in much the same manner as the frame shown in FIG. 8 so as to permit the seat to be extended to accommodate persons of different size. Threaded studs and locknuts may be further provided to lock the seat in the extended position.

Hand holds 61 and 62 may be formed in the inclined member as shownin FIG. 3. It has been'found that providinga place on the device for the patient to holdwith his free hand, especially during the placing of as casts, gives the patient a place to steady himself and a place to grip during moments of pain.

FIG. shows the device used in the supine position for emergencies as noted at the beginning of this specification. Notice that the contoured portion of the inclined member is positioned to cradle the head and neck of the individual to give him a firm comfortable support. In addition, the device may be used as standby equipment for disaster relief for seating injured persons in hallways of hospitals or disaster stations. When assistance is available, the patient can be lifted together with the seat to a gumey where he can be wheeled to the X-ray room and then to the room for applying casts.

A patient can be easily pivoted from the position shown in FIG. 10 at the position shown in FIG. 7 in readiness for a cast.

Note how the tilted position results in the arm hanging in a dependent attitude and free of the body permitting the application of a cast to all parts of the hand, wrist, forearm and upper arm without meeting interference with the patients body. It has been further found that with a patient seated on the inclined board, X-rays may be taken ofthe patient without removing him from the device.

In operation, the torso tilt board is set up from the collapsed position from storage by raising the inclined member to approximately the correct tilted position. The bracing is then moved upwardly about its pivot point until the angle is brought into contact with the adjacent crossmember. The locking means automatically locks the two members together. The inclined member is then extended to the correct length to accommodate the height of the person. The seat is then raised or lowered to the correct angle by loosening the locknuts, moving the wedge along the frame and tightening the locknuts. The patient then sits on the device either in the position shown in FIG. 10 or FIG. 7 according to his injury and for the purpose to be served by the device.

A unique construction locks the bracing to the inclined member. Protrusions 66 and 67 are welded to the angle member 31 at an angle of less than 90 from the bearing of pin 34. The protrusions register with openings 68 and 69 formed in crossmember 24. Similar openings are provided in crossmembers 40. Thus the protrusions and the pin form a wedgelike grip preventing collapse of the board regardless of the way in which the assembly is picked up and carried.
